The Tattvartha Sutra — 'That Which Is' — is the first systematic guide to the eternal wisdom of Jainism, composed in Sanskrit by the philosopher-monk Umasvati nearly two thousand years ago. Revered by every Jain tradition, this concise sequence of sutras maps the nature of reality, the journey of the soul, and the mechanics of karma with breathtaking clarity. This modern-English edition renders Umasvati's timeless teaching in warm, accessible language while remaining faithful to the original's meaning and spirit. Here you will encounter the six substances that make up the universe, the seven categories of truth, the five great vows of nonviolence and truthfulness, and the path by which karma is stopped, shed, and dissolved into liberation. Whether you are new to Jain thought or returning to a beloved classic, this edition invites you to sit with one of the world's most profound maps of the inner life.
